Definition of Harmonic Mean (H.M.) Harmonic Mean of a set of values of a variable gives a measure of their central tendency and is defined as the reciprocal of the arithmetic mean of the reciprocals of the variable values. Clearly, harmonic mean becomes undefined when anyone variable value is zero. The formula of Harmonic Mean: […]
H.M.
Relation among A.M., G.M. and H.M.
(a) For any two positive numbers. A.M. ≥ G.M. ≥ H.M. Proof : let x1 and x2 be two the two positive numbers. therefore their, (b) for pair of positive number A.M. × H.M = G.M.2 Proof : let positive number be x1, x2. therefore, Example: The A.M. and G.M. of two number are […]
